CROSS REFERENCE TO A RELATED APPLICATIONS

This application claims priority to European Community Plant Variety Office (CPVO) Plant Breeder's Rights Application No. 2021/2736 filed on Nov. 1, 2021, under 35 U.S.C. 119(f), the entire contents of which is incorporated by reference herein. This application is also related to U.S. Plant Patent Application filed for a plant derived from the same breeding program that is entitled Sanguisorba Plant Named ‘Red Dream’ (U.S. Plant Pat. No. 32,441) and Sanguisorba Plant Named ‘Big Dream’ (U.S. Plant Pat. No. 33,601). This application is co-pending with U.S. Plant Patent Applications filed for plants derived from the same breeding program that are entitled Sanguisorba Plant Named ‘Tough Dream’ (U.S. Plant patent application Ser. No. 17/752,844), Sanguisorba Plant Named ‘Sweet Dream’ (U.S. Plant patent application Ser. No. 17/752,840).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sanguisorba officinalis and will be referred to hereafter by its cultivar name, ‘Fall Dream’. ‘Fall Dream’ represents a new Burnet, an herbaceous perennial grown for landscape use.

The inventor discovered the new cultivar, ‘Fall Dream’, as a chance seedling in a trial garden in September of 2018 in Rijnsburg, The Netherlands. The parentage is unknown.

Asexual propagation of the new cultivar was first accomplished by division in 2018 by the inventor in Rijnsburg, The Netherlands. Asexual propagation by division has determined that the new cultivar is stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Fall Dream’ as a unique cultivar of Sanguisorba.

-   -   1. ‘Fall Dream’ exhibits late flowering in September through         October in The Netherlands.     -   2. ‘Fall Dream’ exhibits inflorescences that are large in size         and deep burgundy-red in color     -   3. ‘Fall Dream’ exhibits suitability as a container plant.     -   4. ‘Fall Dream’ exhibits stamen filaments that are red-purple in         color.

‘Fall Dream’ can be most closely compared to Sanguisorba officinalis cultivars ‘Big Dream’, ‘Red Dream’, ‘Tough Dream’, and ‘Sweet Dream’. ‘Big Dream’, ‘Red Dream’, ‘Tough Dream’, and ‘Sweet Dream’ are all similar to ‘Fall Dream’ in having upright, plant habits and tall plant heights. ‘Big Dream’ differs from ‘Fall Dream’ in having inflorescences and stamen filaments that are grey-purple in color. ‘Red Dream’ differs from ‘Fall Dream’ in having smaller inflorescences, a smaller plant size, and filaments that are white in color. ‘Tough Dream’ differs from ‘Fall Dream’ in having smaller inflorescences and stronger branches. ‘Sweet Dream’ differs from ‘Fall Dream’ in having flowers that are pink in color.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the overall appearance and distinct characteristics of the new Sanguisorba. The photographs were taken of a one-year-old plant of the new cultivar as field grown outdoors in Rijnsburg, The Netherlands and placed in a container for the photographs.

The photograph in FIG. 1 illustrates the overall habit and appearance of ‘Fall Dream’ in bloom.

The photograph in FIG. 2 provides a close-up view of the inflorescences of ‘Fall Dream’.

The photograph in FIG. 3 provides a close-up view of the foliage of ‘Fall Dream’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and color values cited in the detailed botanical description accurately describe the colors of the new Sanguisorba.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of one-year-old plants from a division of the new cultivar as field grown in Rijnsburg, The Netherlands.
